gas-burners for heating and lighting purposes..

The object of my invention is to provide a new and improved gas-burner,which is simpie in construction, consumes the gas perfectly, produces anintense heat, and is very economical.-

In the accompanying drawings, in which like letters of referenceindicate like parts in all the igures, Figure l is a vertical transversesectional view of my improved gasburner as adapted for lightingpurposes. Fig. 2 is aplan view of the slotted cupped disk. Fig. 3 is adetail transverse sectional view of part of the same.

A gas-supply tube A is provided with a Bunsen-burner attachment B, whichmay be of any conventional type, but is here shown as a ball or globemade of netting or perforated material. The free end of this pipe A isconnected with a disk C, having a downwardly-extending flange D.Preferably this disk and its flange are made hollow, so that this hollowdisk will have a bottom E. The disk is provided with a central openingF, over which is placed a cupped plate J, having a series of radialslots K,so shaped and formed that the edges of the slots overlap, asshown in Fig. 3. The mixture of gas and air escapes through the slots K,where it is ignited and V burns with an intense blue ame of circularshape and occupies horizontally the space bounded by the edge of thefiange D.

For the purpose of heating the mixture of gas and air to a greaterdegree before it is consumed a flanged or plain partition G may beprovided in the hollow disk C, compelling the gas to circulate throughthe space between the top of the hollow disk lC and the partition G,then under the iiange of this partition and up through the space betweenthe under side E or bottom of the hollow disk C and the under side ofthe partition G to the cupped plate J.

To increase the draft, a hood M is provided over the hanged hollow diskC, the products of combustion escaping through the top neck M of saidhood, and for the purpose of preventing fluctuation of the darne a cap Nissecured on the supply-tube A, its bottom edges extending down to nearthe hood M.

For the purpose of preventing currents-of air from disturbing the flamewhen used for lighting a globe O is secured beneath the burner and isprovided with means for the purpose of admitting air either at thebottom Vor some otherconvenient place.

When the burner is to be used for lighting purposes, a disk L ofincandescent materialsuch as used, for example, in making mantles forburners-is suspended or held in the bottom opening of the anged disk Gand is heated to incandescence by the iiame. A screen H may be placedacross the opening F 'for the purpose of more thoroughly mixing disk,having aiiange formed along its outer edge, of a gas-outlet on the underside of said disk, and means for supplying a combustible mixture to saidgas-outlet, substantially as set forth.

3. In`a gas-burner, the combination with a disk, having a flange formedalong its edge, and having a slotted gas-outlet device on its underside, of means for supplying a mixture of gas and air to said slottedgas-outlet device, substantially as set forth.

It. In a gas-burner, the combination with a flanged disk, of a slottedcupped plate -held against said disk, the edges of the slotsoverlapping, and means for supplying a mixture of gas and air to saidcupped slotted plate, substantially as set forth.

5. In a gas-burner, the combination with a flanged plate, of a slottedgas-outlet device on the under side of said plate, the edges of IOO theslots overlapping, and means for supplying a mixture of gas and air tosaid gas-outlet device, substantially as set forth.

6. In a gas-burner, the combination with a hollow iianged disk, havingan opening in its under side, means for supplying a mixture of gas andair to said hollow disk, and a cupped slotted plate held over theopening in the under side of said disk, substantially as set forth.

7. In a gas-burner, the combination with a hollow lianged disk, havingan opening in its under side, of means for supplying a mixture of gasand air to said hollow disk, a piece of netting extending across theopening in the under side of the disk, and a cup-shaped slotted plateheld over said opening, and on the under side of the hollow disk,substantially as set forth.

8. In a gas-burner, the combination with a ilanged hollow disk, of apartition in the same, means for supplying the mixture of gas and air tosaid hollow disk, and a cupped slotted plate held over the opening inthe under side of the hollow flanged disk, substantially as set forth.

9. In a gas-burner, the combination with a flanged disk, of means forsupplying a mixture of gas and air to the same, a cupped slottedburner-plate held on the under side of the disk, and a hood extendingupward over said disk, substantially as set forth.

ted burner-plate held on the under side of the disk, and a hoodextending upward over said disk, and a cap extending downward to nearsaid dome, substantially as set forth.

ll. In a gas-burner, the combination with a ilanged disk, of a cuppedslotted burner-plate held on the under side of the same, means forsupplying a mixture of gas and air to said cupped plate, a hoodextending over the anged disk, and a globe provided with an openingsuspended from said hood, substantially as set forth.

12. In a gas-burner, the combination with a disk, the under side ofwhich is recessed, of a slotted cupped plate held against the recessedside of said disk, the edges of the slots in said cupped plateoverlapping, and means for supplying a combustible mixture to saidcupped slotted plate, substantially as set forth.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, this 31st day of March, 1902.
